This baffles me that it even happened, as despite being increased- as per the server host- the odds of both a shiny and a ditto happening in the same combat are still astronomically low.

The bug:
While playing on a Multiplayer server, I found a shiny Galarian Zigzagoon. After catching it in my first throw, using my only premier ball (to match the color scheme), the battle mentioned the fact that it was actually a ditto. Seen in the image attached is the ditto in question, still holding the revive that Zigzazgoons have a 5% chance (according to the wiki) of holding, but it is NOT shiny.

Do dittos have the ability to "trick" the player into catching fake shinies, or is this a bug and the ditto is MEANT to be shiny, but isn't?

Considering how rare this situation is, I made this ticket. Any kind of clarification would be greatly appreciated!
I do not currently have a list of the included datapacks in the multiplayer server, but I will investigate them if this turns out to not be a universal Pixelmon 9.0.4 issue.

Testing in single player with 100% odds for both shinies and ditto transforms yields the same results.

Both dittos caught IN battle and caught OUT of battle seem to all be turning into normal dittos, even despite the fact that shinies have a 100% rate.

Hello and thank you for your report! I was able to confirm this by increasing the ditto chance and spawning in shiny Pidgeys. When caught and it was a ditto it wouldn't transform into a shiny.
